  Why learning Haskell/Python makes you a worse programmer

I've found, contrary to what you sometimes read, that learning Python and Haskell has not improved my programming using other languages. Haskell in particular, being so different from imperative languages, is supposed to give new insights into programming that will help you even when you are not using the language. My current experience doesn't exactly tally with this, and here is why:Demotivation.I find I think in Python, and even in Haskell to some extent, even though I have used Has...

  Common Lisp is the best language to learn programming

Now that Conrad Barski's Land of Lisp (see my review on Slashdot) has come out, I definitely think Common Lisp is the best language for kids (or anyone else) to start learning computer programming.Between Land of Lisp, David Touretzky's Common Lisp: A Gentle Introduction to Symbolic Computation (really great book for people new to programming, available for free) and The Little LISPer (3rd edition, editions four and up use Scheme) you have three really great resources to get started.Lisp's synta...

  Use DTrace to diagnose gdb issues

A few days ago, I installed the newest 64-bit gdb program (version 7.7.1) on Solaris 10 (X86_64 platform) to debug programs. After playing with the gdb a day, I found 2 issues about gdb:(1) The "set follow-fork-mode child" command doesn't take effect. By default, after the parent process forks the child process, the gdb will track the parent process, so this command can make gdb begin to follow the child process. But this command works OK on Linux.(2) The gdb can't parse the 32-bit application c...
